ROLLER-BEARING.

Specification of Letters Patent.

Application filed April 27, 1908.

Patented June 18, 1912..

Serial No. 429,312.

To all whom it may concern:

Be it known that I, EZRA DEDERIOK, residing in Wisconsin Veterans Home,in the county of WVaupaca and State of Wisconsin, have invented new anduseful Improvements in Roller-Bearings, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

This invention has for its object to provide a bearing for automobiledriving shafts for use in automobiles of the buggy type in which therear or driving wheels are mounted on a turning shaft which is journaledon the springs of the body portion.

An object of the invention is to provide such a machine with a shaft andbearing construction, which while permitting practically frictionlessturning of the driving shaft prevents end thrust thereof and securelyprotects the bearing parts from dust.

With the above and other objects in view the invention consists in thebearing as herein claimed and all equivalent-s.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in the different views:

Figure 1 is a sectional plan view of the driv ing shaft and its bearingsconstructed in accordance with this invention; Fig. 2 is a sectionalview of one of the shaft bearings; and, Fig. 3 is a sectional elevationof one of the shaft bearings and the part to which it is secured.

In these drawings 15 represents the rear springs of an automobile tosupport the rear end of the body thereof, said springs being connectedat their lower parts by reach bars 16 with the fifth wheel of thevehicle.

The ordinary fixed rear axle of a buggy is replaced by a turning shaft17, which is journaled in roller bearings connected to the lower partsof the springs 15, such bearings being formed by casing sections 18clamped together upon the lower parts of the springs 15 and to the reachbars 16 by means of clips 19 as shown in Fig. 3. Each section 18 of thebearing casing is of an open box like formation and has projecting lugs20 to which pins 21, preferably bolts,

are fastened to form supports for pairs of rollers 22, each pin havingtwo of the rollers thereon and the rollers being of a truncated coneshape and bearing against each other at their smaller ends. The shaft 17is reduced in diameter for a distance just sufficient to receive thepairs of rollers 22 between its shoulders 23 formed by such reduction,and as the rollers are prevented from longitudinal movement on their pinsupports by bearing against bosses on the sides of the bearing casing,the engagement between the large ends of the rollers and the shoulders23 of the shaft prevents longitudinal movement of the shaft in eitherdirection, thus overcoming the end thrust thereof. The rollers 22, ofcourse, facilitate the freedom with which the shaft 17 may turn,reducing its friction to a minimum and leaving no unnecessary playthereof.

The shaft may be provided with any suitable driving connection such asthe sprocket wheel 27. keyed thereon and contained within the casing 28and forming a brake drum 29 surrounded by a brake strap 30.

In order that the bearings may be properly lubricated the top bearingsection 18 has an oil cup 31 threaded therein to drop oil onto thereduced portion of the shaft from which it will be taken up by therollers and carried to their bearings.

What I claim as my invention and desire to secure by Letters Patent is:

A roller bearing comprising a rotary axle having a reduced portionforming opposite shoulders, a casing surrounding the reduced portion ofthe axle and having bosses formed thereon, pins extending across thecasing and through the bosses, and pairs of conical rollers on the pinswith their smaller ends together and wit-h their other ends bearingagainst the bosses on the sides of the casing and against the shouldersof the axle to prevent longitudinal movement thereof.

In testimony whereof, I aflix my signature, in presence of twowitnesses.

EZRA DEDERICK.
